Analyze final destinations
The last click is the final category users select, indicating where they believe they’ve found the correct information. If users' first clicks are correct but the success rate is low, it suggests that lower-level categories overlap too much, confusing users as they navigate deeper into the structure. For instance, if users initially click "Vegan Products" correctly but then struggle to find vegan yogurts among "Tofu Products" and "Lactose-Free," it indicates a need for clearer distinctions between these subcategories.
